Answer to Question 1

A, B, C
Feedback:
The skin is the first line of barrier defense, creating a physical barrier to prevent pathogens from entering the internal tissues. Mucous membranes are another barrier defense protecting the area without skin protection (e.g., the respiratory tract, gastrointestinal tract, genitourinary tract). Gastric acids destroy many pathogens that are ingested or swallowed, preventing them from entering the bloodstream or internal organs. Leukocytes and T cells are cellular defenses and not barrier defenses.

Answer to Question 2

A
Feedback:
Baclofen is used for treatment of muscle spasticity associated with neuromuscular diseases such as multiple sclerosis. Cyclobenzaprine, metaxalone, and orphenadrine are used for relief of discomfort associated with painful, acute musculoskeletal conditions.
